Re: scsh: stream_char_readyp

There is similar code in Emacs.  Look at the s-gnu.h file in the Emacs
sources and and what it does for this.  Make sure to conditionalize properly
on _STDIO_USES_IOSTREAM, since the iolib definition (the one you cited for
linux) will eventually become the right one for hurd too.
